Semantics- oriented systems
They include the logical-analytical
systems, which provide the automatic extraction of semantic information
from documents and their use for the solution of the problems, which relate to
the class of intellectual.
Semantics-oriented systems are the new
class of systems. Similar systems for different fields of application were
developed within the framework of commercial projects of IPI RAN (Institute for
Informatics Problems Russian Academy of Science): DIEZ, Criminal, LINGVO-
MASTER and other
For this aims the tools
of construction Knowledge Base (KB) and corresponding procedures of the
meaningful texts processing were created. We transfer of complex linguistic analysis to
the level of processing knowledge. Obtained results are corresponded the newest
scientific research abroad.
The systems are oriented to process the
texts of natural language with the delivery to the user (analyst) the necessary
information in the most understandable form. Standard tasks of the systems:
- Automatic introduction of documents
with their division on the part and lexical analysis;
- Automatic formalization of text
information (texts in Russian and English) with the creation of s own KB;
- Search for similar documents and
mentioned in them (information) objects on the basis of the criterion of their
semantic proximity;
- Answer to the questions in the natural
language;
- Search of objects according to the
connections with other objects;
- Using of statistical methods for the
search for dependences and their representation in the form of temporary
diagrams;
- Automatic forming of information in Data
Bases.
Systems relate to the class of
logical-analytical. These are the complex programs, which automate the process
of introduction, formalization and the analysis of text documents, their use in
the tasks of search and subsequent analysis. Formalization consists in extraction
of the significant information: the interesting user objects (for example, FIO
of the persons, name organizations, cities and others), and also their signs,
connections, the attributes (this they can be property, verbal portraits and
other). They form the structures of knowledge in KB. Each system contains its
own KB, which provide:
- Storage of the significant information
and connections;
- Effective search and data analysis
according to the connections.
Thus, we use the principles and tools of
the construction of the new class of the systems, based on the knowledge
structures.
